It would be nice if there were such a function, unfortunately, there is not.
Here is some untested air code that will do the trick.
Dim lngArrayRows as Long
Dim lngArrayCols as Long
Dim lngFieldCount as Long
Dim lngRowCount as Long
Dim rst as Recordset
lngArrayRows = Ubound(MyArray,0) - 1
lngArrayCols = Ubound(MyArray,1) -1
Set rst = CurrentDb.OpenRecordset("SomeTable", dbOpenDynaSet)
For lngLRowCount to lngArrayRows
With rst
.Add
For lngFieldCount = 0 to lngArrayRows
.fields(lngFieldCoun) = MyArray(lngRowCount, lngFieldCount)
Next lngFieldCount
.Update
End With
Next lngRowCount
